To all whom it may concern:

Be it known thatI, JAMES W. EARLEs, a citizen of the United States,residing at Fort Hancock, in the county of Monmouth, State of NewJersey, have invented certain new and useful Improvements in Omnigraphsand I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The present invention relates to omni graphs. a

In devices of this class, which, as is well understood, are utilized bytelegraph-operators in practicing receiving and sending telegraphicmessages, it has been found necessary to make use of a key circuitedwith. a battery and sounder, as well as a revolving disk provided with aseries of projections corresponding to the characters of a telegraphicalphabet and a resilient finger adapted to contact with saidprojection-s during the rotation of the disk, so that the operator afterbecoming acquainted with the soundf so to speak, of legach letter maypractice the same upon the it is the object of the present invention tosimplify this construction by utilizing a single key, which is adaptedfor use both to contact with the plate projections ina manner similar tothe spring-finger of the construction above referred to and also to beused in the ordinary manneras a telegraph-key in practicing sounding theletters.

A further object of the invention is to sim-.

plify the old construction by substituting for the revolving disk asingle arc-shaped plate provided on its inner edge with. the projec-'tions which correspond to the letters of the telegraphic alphabet, ahorizontially-movable key being utilized in connection with said plateand provided with a forwardly-ex tending finger. adapted to be movedinto 0011- tact with the projections on said plate, the key and platebeing electrically connected with the usual sounder. I

Further objects of the invention will be set forth at length in. thefollowing detailed de-' side elevation thereof, showing the normal orinoperative position of the key. Fig. 3 is a similar view showing thekey in its operative position. Fig. 4 is a fragmental view of Fig.1,'showing the locking-switch engaged with thesupport for the key. Fig.5 is'a front view of the key-support. Fig. 6 is a section on the line 66 of Fig. 1, showing the mounting for the key-support. Fig. Tis a sideview ofthe key. Fig. 8 is a perspective view-of the spring-contactfinger carried by the key.

Referring more particularly to the drawings, 10 designatesthe base-plateof the device, upon which is mounted .an arcuate metal plate 11,provided at opposite ends with elongated openings 10 for the screws 11',by means of which said plate is held in spaced relation to the upperface of the'baseplate, one of said screws being connected with one ofthe terminal wires a of a battery I), circuited with a'sounder c, whichis in turn connected with a binding-post (1, carried by the base-plateand connected by the wire e, with a second arcuate plate 12, mountedupon the base-plate means of screws g, one of which serves as" the binding-post to which the end of the wire eis attached. Plate 12 is formedconcentric with plate 11 and is o positely disposed with respectthereto, a p ate 13, likewise of arcuate shape, being interposed betweenplates 11 and '12 adjacent the former and concentric therewith. Mountedin theupper face of the baseplate is a metal plate v14:, provided withan opening 14', through which the stem 15 of a pivot post or rod 16extends, said rod being hcldin place therein by means of a second plate17, which fits beneath plate 14, and is likewise provided with anopening through which the pivot-stem extends, plate 17 being' secured.in place by means of pins 17, which are removably inserted in socketsformed in the sides of the stem. The extreme'lower end of said stem isreduced, as indicated by the reference-numeral 18, and fits in'a similarsocket 18, formed in a plate 19, disposed on the under face of the base.

The pivot-rod is further provided with an annular plate 20, located atthe upper portion of its stem, the under face of said'plate bearingagainst the upper face of the. plate 14. Plate 20 is provided with alateral extension 21.

Thev upper portion of the pivot-rod termi- 5 nates in a pair of arms 22,diverging from each other and forming a yoke, each arm having a screw 23working through an opening formed therein and carrying a lock-nut 24, bymeans of which said screws are retained in adjusted position.

The key 25, which is pivotally mounted between the arms of said yoke, isprovided intermediate its ends upon opposite sides with the lateralextensions or shoulders 26, each of which carries a pin 26, whose sharp'cued end its in a socket formed in the corresponding adjusting-screwend, whereby the key will have a rocking movement in a vertical planewith respect to said pivot-rod. The rear end of said key carries theusual opcrating-handle 27, while its opposite or front end has securedthereto a small resilient metal plate 28, which is bent to form aforwardly-extending finger 28,' which-is adapt-- ed to contact with aseries of inwardly-extending projections f f formed on thelnner edge ofplate 11,during the.horizontal movement of said key, as hereinafter morefully described. 'Key 25 isfurther provided to- 0 ward its rear andfront ends with a pair of screws 29 and 31, which work through openingsformed therein, the screw 29 fitting within the coils of a spiral spring30, one end of which is attached to the upper face of the extension 21of plate 20, while its opposite end bears against the under face of thekey 25, thus normally holding the rear or handle end of the key inelevated position, its opposite end being dis osed adjacent the spacebetween the base-p ate and plate 11, with the lower end of screw 31resting on the arcuate plate 13.

Disposed on the underface of the key bctween thescrew 29 and the endthereof is a depending metal pin 32, which is adapted to" travel acrossthe upper face of plate 12, which is divided into a series of spaces h,each of which is marked with a letter corresponding to the diagonallyopposite character formed by the projections ff" on the plate 11. Eachspace on the plate 12 is separated from the adjacent spaces by a narrowtransverse shoulder it. As. above stated, each set of projections on theplate 11 corresponds to the diagonally-opposite letter on the plate 12,the blunted projections f corresponding to the dashes of a letter of theordinary telegraphic alphabet and the sharpened projections f in likemanner to the dots, so that each group ofprojections on the plate 1.1forms a single letter. Itwill thus be apparent that the key maybe swungon its pivot until the pin 32 is directly above the letter to be formedor sounded, when the key will be depressed in figthusual manner andagain moved horiz *1- of any letter.

tally to .bring the finger 28 on the plate 8 across the projections ofthe corresponding letter on plate 11, the make and break of the electriccircuit caused by the movement of the finger across the projectionsoperating the sounder c in the usual manner, and thus indicating theprecise sound telegraphically It will be equally obvious that while thekey is normally swung or moved from right to left, as indicated by thearrows in Fig. 1, it may be moved in the opposite direction to make orform the letters N, V, R, &c., which are the reverse of the letters A,B, and C.

After the sound of any desired letter is obtainedand the operatordesires to practice forming such letter a locking device isswung intoengagement with the key-pivot and any horizontal movement thereofprevented, so that the key may be utilized and operated in, the ordinarymanner merely as a sender. I To this end there is pivotally mounted upona bolt 33, aiiixed to the base-plate. a lever 34,

provided at one end with a laterzilly-extending finger 35, adapted tobereceived in a notch 35, formed in'the plate 20, thus checking anytendency of the pivot to 1 turn and limiting the movement of the key toits rocking or vertical movement. 1

Lever 34, which is provided with an operating-handle 36 at its oppositeend, is circuited with the plate 12 by the wire i, one end of whichisconnected to the binding-screw 1 1 and the other end to the bolt 33,the lever thus forming a switch and disposed normally Furtherdescription of the device and its manner of operation is thoughtunnecessary in view of the foregoing, it being understood that when thekey isbeing moved horizontally the circuit is closed through the contactof pin 32 with plate 12 and the spring-finger 28 with the projections onthe plate 11, the circuit being made and broken alternately during thepassage of said finger over such projections.
